Abstract:
This invention provides an adaptive monitor and support system that adapts a monitoring process for monitored devices based on monitored data by downloading instructions and/or monitor/support programs to optimize the monitoring process. A monitor/support shell executes in intelligent monitored devices such as personal computers. For non-intelligent devices, intelligent monitor devices are provided to support the monitor/supporting shell. A profile corresponding to each monitored device identifies device functions that require special monitor and/or support processes which are downloaded from an adaptive monitor and support device located remotely relative to the monitored device. The adaptive monitor and support device analyzes uploaded monitored data and adjusts the monitoring process based on the analysis results by downloading special monitor programs, special support programs, and/or instructions to the monitored devices. The special monitor and/or support programs may also be downloaded directly from third-party databases.
Abstract:
A balanced modulator, producing a double sideband suppressed carrier (DSBSC) output achieves carrier suppression and linear performance suitable to modulate frequency division multiplexed signals with stringent interchannel interference requirements. It is simply and inexpensively realized through the use of two logic gates which are arranged in a dual complementary fashion, so that their output terminals go high and low alternately, and which drive a center-tapped transformer through coupling capacitors to provide the required switching function necessary to produce the DSBSC output. The modulator circuit has the added feature that the square wave carrier source that is applied to the logic gates can be the means of activating the circuit, thereby eliminating the need for a separate power supply.
Abstract:
An apparatus and method for speech-text-transmit communication over data networks includes speech recognition devices and text to speech conversion devices that translate speech signals input to the terminal into text and text data received from a data network into speech output signals. The speech input signals are translated into text based on phonemes obtained from a spectral analysis of the speech input signals. The text data is transmitted to a receiving party over the data network as a plurality of text data packets such that a continuous stream of text data is obtained. The receiving party's terminal receives the text data and may immediately display the text data and/or translate it into speech output signals using the text to speech conversion device. The text to speech conversion device uses speech pattern data stored in a speech pattern database for synthesizing a human voice for playing of the speech output signals using a speech output device.
